Inventor: SATO TAKAHIRO
IPC: G11B5/265
Filed: 1986-07-08
Abstract: PURPOSE:To obtain a magnetic head by providing the notched parts only on the outside cores of a recording/reproducing head and an erasion head to pre scribe the track width of each head with no notched part provided on a center core. CONSTITUTION:A notched part 2 is provided on a 1st core 1 to prescribe the track width of a recording/reproducing head and the core 1 is integrated with a 2nd core 3 by glass bonding. Thus the recording/reproducing head is obtained. While another notched part 2 is formed on a 4th core 4 to prescribe the track width of an erasion head. The core 3 is integrated with a 3rd core 5 by glass bonding for production of the erasion head. Then a nonmagnetic layer 6 is provided between both cores 3 and 5 for production of a magnetic head 7. Thus it is possible to secure high intensity together with a large section area of a magnetic path for the head 7 even through the inter-gap distance 9 is reduced less than 0.5mm since both cores 3 and 5 have no notched part. Therefore the recording/reproducing characteristics are improved for the head 7.

Title: Preparation of aluminosilicate of high purity
Inventor: UMEHARA YOSHIO
IPC: C01B33/26
Filed: 1978-12-27
Abstract: PURPOSE: To manufacture the titled salt simply by a method wherein a silicate is added to an Al working waste liquor, which is produced by adding carbon particles, magnetite impalpable powder or one portion of an aluminosilicate obtained and is refined.  
     CONSTITUTION: Impurities contained in an Al working waste liquor are difficult to be removed, but the impurities cohere on the outer circumferences of additives when adding carbon particles, which do not react with caustic soda, magnetite powder or a small quantity of one portion of an aluminosilicate acquired by preceding treatment, and deposits, which are easy to be filtered, are formed. Thus, the Al working waste liquor is refined easily and simply. When adding a silicate such as sodium silicate to the Al working waste liquor refined, the silicate reacts with sodium aluminate in the waste liquor, and sodium aluminosilicate with high purity is precipitated, and separated from NaOH in the waste liquor.

Filed: 1989-06-22
Abstract: PURPOSE: To maintain the coherence of data by processing only an invalid queue input which had been valid before a read transaction is performed before receiving read data. CONSTITUTION: A system bus interface 18 copies a valid bit 44 to a flash bit 46 for all the inputs in an invalid queue 38 at the time of sending the read transaction to a main memory on a system bus 12. Then, all the inputs 40 which had been valid when the read transaction are generated set the flash bit 46 and all the inputs 40 which had not been valid reset the flash bit 46. A CPU module 14 accesses input data stored in a read data queue 36 after processing all the invalid states of the invalid queue 38 for which the flash bit is set. Thus, the invalid states are correctly made serial and a shared data protocol is correctly operated.

Filed: 1992-06-19
Abstract: PURPOSE:To make a vacuum pressure measuring unit unnecessary, and to adequately perform developing by measuring the vacuum pressure of a developing groove loop based on the current of the motor of a vacuum pump. CONSTITUTION:The device is provided with a transistor 11 having a switching function turning on/off the current of the vacuum pump 7, a pump on/off controlling part 12 performing the on/off control of the transistor 11, and a controlling part 15 inputting a digital value, judging whether the vacuum pressure of the developing groove 41 is adequate or not based on the current of the vacuum pump 7 and performing necessary controlling. Since there is correlation between the vacuum pressure of the developing groove 41 and the current value of the driving motor of the pump 7, the vacuum pressure of the developing groove 41 can be measured by the current value of the driving motor of the pump 7. Consequently, since whether the vacuum pressure of the developing groove 41 is adequate or not can be judged by comparing the current value of the driving motor of the pump 7 with reference value by means of a negative pressure judging means, the vacuum pressure is not required to be directly measured.
